One where ratio can be programmed in SW + and the other where it gets the information from ratio estimator module. + + It supports sample rate conversions in the range of 8 to 192 kHz and + supports 6 streams upto 12 total channels. The input data size can be + 16, 24 and 32 bits. + +maintainers: + - Jon Hunter <jonathanh@nvidia.com> + - Mohan Kumar <mkumard@nvidia.com> + - Sameer Pujar <spujar@nvidia.com> + +allOf: + - $ref: dai-common.yaml# + +properties: + $nodename: + pattern: "^asrc@[0-9a-f]*$" + + compatible: + oneOf: + - const: nvidia,tegra186-asrc + - items: + - enum: + - nvidia,tegra234-asrc + - nvidia,tegra194-asrc + - const: nvidia,tegra186-asrc + + reg: + maxItems: 1 + + sound-name-prefix: + pattern: "^ASRC[1-9]$" + + ports: + $ref: /schemas/graph.yaml#/properties/ports + description: | + ASRC has seven input ports and six output ports.
